Biomechanical properties of different external fixator frame configurations.
External fixators are easy to apply and maximize soft tissue preservation. However, frames need providing an adequate stiffness in order to avoid excessive interfragmentary movement during the healing period. We characterized the stiffness of four different configurations of the newly developed Hoffmann 3 external fixation system. ⋯ The diameter and the amount of used connecting rods as well as the adequate placement of these rods towards the main loading directions determine the construct stiffness. These results could help the surgeons estimating how different frames can potentially affect the interfragmentary motion. This information might help in choosing specific configuration when treating different fracture types on given patients.

Nonoperative management has become the surgical treatment of choice in the hemodynamically stable patient with blunt hepatic trauma. The increased use and success of nonoperative management have been facilitated by the development of increasingly higher resolution computed tomography imaging, improved management of physiology and resuscitation (damage control), and routine availability of interventional procedures such as angiography and embolization, image-guided percutaneous drainage, and endoscopy. ⋯ A systematic and logical approach to the control of hemorrhage is required in the operating room. Thorough knowledge of the anatomy and surgical techniques, such as perihepatic packing, effective Pringle maneuver, hepatic mobilization, infrahepatic and suprahepatic control of the IVC, and stapled hepatectomy, is essential.
